Hi,
yes that would nice.
The modulemap issue can be fixed by adding a -resource-dir flag. Going with a
comment in AddSwift.cmake, I switched the include fag to the library output
directory to "-resource-dir”, but then SwiftShims wouldn’t build. So I changed
the flag back to a standard include and make it *also* specify “-resource-dir”
on cross-compile (so the cross command has both -I and -resource-dir). Now the
native host builds, but the cross-compiled stdlib won’t because of the same
SwiftShims issue.
So I need to look at how the compiler uses -resource-dir what’s going on with
SwiftShims.

Explanation on the flags, process:
${cc_files} = the place where I stick the cross-compile resources. Somewhere
the stick the output package later.
${toolchain}:
Built from: https://launchpad.net/gcc-arm-embedded/5.0/5-2015-q4-major
Edit install_toolchain.sh and add “--enable-gold” to the binutils flags
Also in install_common.sh, charged TARGET to "arm-linux-eabi”, but not sure
that’s necessary.
Give the path to the unprefixed versions of the tools, e.g:
"${cc_files}/toolchain/gcc-arm-none-eabi-5_2-2015q4/install-native/arm-linux-eabi/bin"
${sysroot}:
